Convert String to NSDate in Swift

Question

How to convert this date to NSDate

datestring = /Date(147410000000)/   //String from server response

Expected Output:

12/01/2014

I tried this. But I got nil.

let dateFormatter:NSDateFormatter = NSDateFormatter()
dateFormatter.dateFormat = "dd/MM/yyyy"
let date = dateFormatter.dateFromString(datestring)
return date

Does this help? http://stackoverflow.com/questions/1757303/parsing-json-dates-on-iphone — Mike Taverne, Oct 28 '14 at 05:48

"147410000000", i think this the time-interval which you are getting from server.

In your case,you need to trim the string and convert it From /Date(147410000000)/ to 147410000000

    var string : String = "1408709486" // (Put your string here)

    var timeinterval : NSTimeInterval = (string as NSString).doubleValue // convert it in to NSTimeInteral

    var dateFromServer = NSDate(timeIntervalSince1970:timeinterval) // you can the Date object from here

    println(dateFromServer) // for My Example it will print : 2014-08-22 12:11:26 +0000


    // Here i create a simple date formatter and print the string from DATE object. you can do it vise-versa. 

    var dateFormater : NSDateFormatter = NSDateFormatter()
    dateFormater.dateFormat = "yyyy-MM-dd"
    println(dateFormater.stringFromDate(dateFromServer)) // And then i can get the string like this : 2014-08-22

Check the comment section. Martin's comment will also help you to resolve your problem.

"147410000000" gives the time in milliseconds, so you have to divide it by 1000. — Martin R, Oct 28 '14 at 06:17
Thanks Krupanshu! Great solution. Usually sqlite store date as time interval. We can retrieve and reconvert into NSDate with that. — A J, Jun 05 '15 at 09:59

You just use the wrong function at the last line of your above mentioned code

 var dateString = "01-02-2010"
 var dateFormatter = NSDateFormatter()
 dateFormatter.dateFormat = "yyyy-MM-dd"
 var dateFromString = dateFormatter.dateFromString(dateString)

Convert Date format in Swift:

let myDate = "2016-09-19 01:25:17"
let dateFormat = NSDateFormatter()
dateFormat.dateFormat = "yyyy-MM-dd HH:mm:ss"

let date = dateFormat.dateFromString(myDate)
dateFormat.dateFormat =  "yyyy-MM-dd"
let  newDate =  dateFormat.stringFromDate(date!)

print(newDate)

What If I need current date always and then pass it to this to get an NSDate instead using a hardcoded string. – Arjun Kalidas Nov 03 '16 at 11:44
Try this: let date = NSDate() dateFormat.dateFormat = "yyyy-dd-MM" let newDate = dateFormat.stringFromDate(date) print(newDate) – Vikram Biwal Nov 04 '16 at 05:06

Based on Wolverine's code, I've written a function for Swift 3 and iOS10. Feel free to use:

func convertStringTimestampToStringDate(_ dateandTime: String) -> String {

let string : String = dateandTime
let timeinterval : TimeInterval = (string as NSString).doubleValue
let dateFromServer = NSDate(timeIntervalSince1970:timeinterval)

let dateFormater : DateFormatter = DateFormatter()
dateFormater.dateFormat = "MMM dd, yyyy, HH:mm a"
dateFormater.amSymbol = "AM"
dateFormater.pmSymbol = "PM"

let backToString = dateFormater.string(from: dateFromServer as Date)
print(dateFormater.string(from: dateFromServer as Date))
return backToString }

This should bring a solution like e.g.: "Oct 20, 2016, 03:30 AM" from an timestamp as input.
